This release has major performance improvements, and adds some attributes for arrows.
Here are some benchmark results for Ubuntu 64-bit 8.04:
| Version | Wall time to construct 10×10x10 cube graph (3701 API calls) | API calls per second |
|---|---|---|
| Python (xmlrpclib), 1 CPU | 6.2 s | 600 |
| Python (xmlrpclib), 2 CPUs | 3.5 s | 1060 |
| C API (xmlrpc-c), 1 CPU | 2.3 s | 1600 |
| C API (xmlrpc-c), 2 CPUs | 2.1 s | 1700 |
| Direct linking with UbiGraph server (not possible with the free version) |
0.004 s | 925000 |
UbiGraph alpha-0.2.4, 23 June 2008
- Lots of performance improvements, and a new section in the user’s guide
about performance tuning - New edge attributes: arrow_position, arrow_length, arrow_radius,
arrow_reverse - New edge stroke kind: “none”, does not draw the edge, but still draws
decorations (i.e. arrowhead and label) - New examples: arrows.py, routing.py
- Bug fix: vertex “visible” attribute not handled properly
